Data acquisition is important in geotechnical and hydrological field investigations. Commercially available data acquisitions systems are often not well suited to field use, and can be costly. An alternative to buying a data acquisition system is to build one, and recent advances in computer micro-chip technology have made it easy to understand, design and build simple data acquisition devices.
The design of a data acquisition system developed at the University of Waterloo, along with an example of its use, is discussed in the paper. The intent was to sample 16 channels at 12 bit resolution for prolonged periods under adverse field conditions. Other design parameters included portability, battery operation, and a sealed unit to guard against moisture ingress.
